学研究的范式——比较静态分析，是一种技术，通过这一技术，理论可以被考察研究，以确定理论的可驳斥假说，它是对进行的一种符合的仿真。具体讲，比较静态分析是通过逻辑运算，模拟理论的可驳斥命题即检验条件是什么，从而为理论的验证提供方法。用经济学的研究范式对陕西省"一线两带"的比较静态分析显示，此战略成立的必要条件之一是：随着战略的实施即政府对极化地区的投入，其产出增加应该比其它地区产出增加大，否则这一战略就不成立。也就是说，如果陕北或陕南经济发展更快，集中投资于西安等中心城市，并不是更好的战略。

The results of the determinating the activity of the CA in vitro showed that the CA of the water—fed individuals were in activing statics after eclosion. Because of the apperence of the Vg in haemolymph and the deposition of the vitellin in oocytes in the unfed females, it was shown that the CA in such individuals were in activiting statics, too. Again because in the water—fed females which did not lack the feeding action the activity of the CA showed dropping tendency gradually still, it could be said that the activiting of the CA was possibly effected by the nutrition but it was never related to the adult feeding action. In another respect, the brain of the female adult had not significant effect on the activiting CA. The oocytes could depositing vitellin in individuals removed brain tissue on the day of eclosion, which showed that the activting of CA was not concerned with brain.

CA活性的体外测定说明饲水个体的CA同样具有活性，不取食个体血淋巴中Vg的存在以及卵母细胞中卵黄的沉积表明，在不取食的个体中CA同样具有活性，所以CA的活化与成虫期的取食动作无关，与成虫是否取食花蜜也无太多的联系，但是CA活性的维持可能受成虫期营养的影响，如果以卵母细胞发育和CA体积大小作为CA活性的指标，则饲水个体CA的活性在后期受到了影响，说明饲水不能替代取食蜂蜜来维持成虫期CA的活性；成虫期脑对CA的活化无明显作用，羽化当日摘除脑的个体，其卵母细胞仍然可以沉积卵黄，说明CA的活化与脑无关，而是受某种不确定的因子的影响；用抗JH物质—早熟素—Ⅱ以10ug／虫的剂量在颈部点滴处理雌虫，对Vg的发生和卵巢的发育具有一定的迟缓作用，其原因有待于进一步的研究。
